Are you really sure you want your dog in the pool? There are safety issues and Golden hair in the filter to think about.

If you do want to do it, the first thing I'd work on is making sure the dog knows how to, and can get itself out of the pool. If the pool has built in steps in the shallow end this should be no problem. You can walk the dog in and out a couple times and if it likes the pool and sees people and/or other dogs jumping from the side it will probably try jumping in itself or you can get in and encourage the dog to jump to you. If you don't have shallow end steps, the dog is going to have to pull itself up over the side to get out, which some dogs can't do.

Some time ago there was a video posted of a mother dog running back and forth frantically at the side of a pool as her pup was struggling to stay afloat. She finally grabbed the pup by the scruff and pulled it out.

We live in SW Florida and we have a lanai with in ground pool. When we got Bree one of the first thing I did was take her in the pool. We picked her up and carried her in. We held her and just stood, gently lowering her in. Then we lowered her in and let her paddle. We let her "swim" between us, moving farther away each time. Always enter and exit the same step and name it, Step. Good Step! She needs to know how to get out. My best advice, get the bright orange retriever for water, make sure she holds it in her mouth to prevent her breathing thru her mouth. Teach Fetch! and release! Good luck!

What I found when teaching my dog was that they aren't scared of the water, but they aren't initially initially sure how to get out. Ruger would only take the steps in and out at first but now all he does is jump in from any angle. They just need to practice and get comfortable.
